MALT-Kl LN.

SPECIFICATION forming part Of Letters Patent NO. 226,860, dated April 27, 1880.

Application filed October 29,1879.

To all whom it may concern:

Be it known that I, JOHN JAKEL, of Detroit, Wayne county, Michigan, have invented an Improvement in Malt-Kilns, of which the following is a specification.

The nature of my invention relates to certain new and useful improvements in the construction of kilns particularly designed for preparing malt; and the invention consists in the peculiar construction, arrangement, and combinations of the various parts, all as more fully hereinafter set forth.

In the drawings, Figure 1 is a sectional perspective. Fig. 2 is a vertical cross-section through the cylinder. Fig. Sis a bottom View of the basket. Fig. etis a vertical longitudinal section of the cylinder.

In the accompanying drawings, which form a part of this specification, A represents a suitable oven, provided with a proper furnace for generating heat. Jourrialed in the end walls of the oven, and at the top thereof, is a cylinder, 0, which may be rotated by means of a pulley, D, upon one of the hollow trunz 5 nions E which project through the walls. This cylinder is constructed of perforated sheet metal or other suitable material, and is provided with an opening, a, which can be closed by a slide, b. To the innerwall of this 0 cylinder are secured the longitudinal wings c and spiral or curved wings d. A hollow shaft, F, extends through the hollow trunnions and the cylinder, its outer ends being supported in suitable brackets Gr secured to the end walls 3 5 of the oven, the shaft being rigidly secured to one or both of such brackets, so as not to interfere with the rotation of the cylinder.

" Rigidly secured to the shaft F, within the cylinder, is a basket, H. This basket is like- 0 wise made of perforated sheet metal, and is provided with hollow partitions f, which are also perforated. The basket is hopper-shaped, and is provided with an opening in its bot tom, which can be closed or disclosed by a 5 slide, g, operated by a rod, h, which slides through the hollow shaft F, and is connected to the slide 9 by the arm 1', which projects downward through a slot, is, in the under side of said shaft.

Below the cylinder, :"nd secured to the walls of the oven, is a perforated hopper, J, terminating in the discharge-pipe K, which leads outside the wall of the oven.

A hinged covering, L, is provided at the top of the oven to inclose, wholly or partially, the cylinder 0.

In practice, after the malt has been prepared for drying through the ordinary pro cesses, a sufficient quantity is introduced through the opening a in the cylinder into the basket, the slidein the bottom of which is closed and the coverings L areshut.

The heat generated in the oven permeates through the perforated cylinder and the hasket. The hollow partitions f, being open at the shell of the basket, allow the heat to pass thoroughly through the malt, thus gradually drying it. During the process of drying the malt has to be frequently or at successive intervals turned over, in order that it may be equally dried, and this ordinarily is performed by manual labor.

In my process I withdraw the slide from the bottom of the basket, allowing the malt to pass into the cylinder, which, being rotated, and by means of the wings upon its inner wall, carries the malt up, letting it fall at every rotation into the basket, and when it is desired to discontinue this operation the slide in the basket is closed, when the continued rotation of the cylinder will deliver all the malt back into the basket, where it remainsuntil a new stirring or agitation is deemed necessary, when the operation last described is again repeated.

Toward the close of the process ahigher degree of heat is required and the agitation is more frequently repeated, which subjects the malt to the greater heat of the cylinder, the operation being carried on until the malt isof the desired color. When this is attained the slides in both the basket and cylinder are opened, thus allowing the malt to pass into the discharge-hopper, from whence it is conducted to a proper receptacle.

hat I claim as my invention is 1. In a malt-kiln, the combination, with a revolving cylinder, of an inclosed stationary basket, with upward open mouth, constructed and arranged substantially as set forth, so that in the revolutions of the cylinder the contents with hollow perforated partitions and slide g,

substantially as and for the purposes set forth.

3. A malt-kiln consisting of an oven, A, per- IO forated cylinder 0, provided with wings upon its inner wall and inclosing a stationary basket, H, provided with hollow partitions f, and a discharge-hopper, J substantially as and for the purposes specified.

In testimony whereof I hereunto set my hand. 15
